Well, I'm not blaming softupdates in this case. But still, problem
exists.
May be I was not clear: cron _didn't_ exit with SIGSEGV, it continued
to run. But it was unable to fork to run cron jobs. I noticed that
after some 10 hours (I'm on dialup, and I just saw no attempts of
my machine to dial to get mail).
Note: 'make buildworld' had already been finished for some 4 hours,
but cron still was in that strange state: running, but all attempts
to fork to run some jobs failed:
May 13 08:50:00 grape /kernel: pid 22955 (cron), uid 0: exited on signal 11
May 13 08:55:00 grape /kernel: pid 22969 (cron), uid 0: exited on signal 11
May 13 08:55:00 grape /kernel: pid 22970 (cron), uid 0: exited on signal 11
The same was with sendmail (in fact because of this my original letter,
which I had written in the morning, remained in queue till evening).
I can imagine what happenes. And I'm not absolutely shure that it is an
error, just would like to hear some authoritative opinion ;)
